Thanks for the replies. I finally found a few days to go home and start construction. I went the EMT/Rivet route as it is super easy to rivet. I will definitely be using the rivet gun for everything.
Similar to the Redneck Boattail I attached the top two bars to the car using existing Kammback holes and bent them until they matched the template. Then I bent the end elliptical piece which was easily the hardest part without a conduit bender. Then I attached the bottom two bars and started making cross members to add strength. I unfortunately ran out of time and conduit so I had to stop. I also tried to at least get the wiring complete but I need a 5 to 4 pole tail light converter for my car and the lights I got for it to work. I will resume production as soon as I graduate in August.
BTW, the boattail extends 36" past the bumper.
